Tyre And Jerusalem II

Two or more different submicroscopic events might correspond to a single macroscopic event. Thus, subatomic quantum indeterminacy, if it exists, need not contradict cosmic causal determinism, if that exists. (I know that chaos has recently invaded the macrocosm but I am here addressing conceptual, not empirical, questions.)

Similarly, two or more different prehistorical events can definitely correspond to single known history. Two scenarios: an ancient city wins a battle and records its victory or the city loses the battle but, for obvious reasons, records a victory in any case. In both scenarios, the record survives and is believed and the truth or otherwise of the matter does not influence later events. Geoffrey of Monmouth states that Arthur, King Of Britain, conquered Ireland whereas Irish legend claims that Finn MacCool defeated Arthur, son of Brit. (That is what we call a guest appearance or crossover.)

Time Patrolman Carl Farness justifies defending his Goths against a Hun incursion because there is no historical record either of that incursion or of its outcome. So to what extent can time travelers monkey around in the past without messing things up? It seems that they can have a lot of elbow room as long as they avoid well documented periods and nexuses.

But I still think that saving appearances after the destruction of Tyre in 950 BC would be a lost cause and a hopeless case.
